v0.1-alpha.12 — one name to chat, one name to pay

Sonar's biggest release yet: one @sonarprivacy.xyz handle now starts an encrypted chat (NIP-05) and receives Lightning payments (BIP-353) from any wallet — plus a production cutover to Signal-style transcripts, the Trill nudge, and mesh/group security fixes from an adversarial review.

How Sonar is built — two networks, one conversation, no phone number
